The Case
On November 22, 1975, a mother reported her three-year-old son missing after seeing him roaming in the vicinity of a wooded area behind their apartment complex in Richmond, VA. His body was found in the river nine miles from his home four days later. The murder garnered tremendous media attention and public outrage, yet the police failed to find a lead or suspect. 20-year-old Marvin Grimm Jr. lived across the hall from the family and, based on two arguments Grimm had with the boy’s father almost a month after the murder, police set their sights on him. After a nine-hour work day, police picked up Grimm and subjected him to another nine-plus hours of interrogation, causing Grimm to break down and confess to killing the boy. Grimm pleaded guilty, and the court sentenced him to life in prison.
